Crystran have been manufacturing optics for over 20 years and specialise in fabricating high spec components from IR and UV materials. Working mainly with crystals and innovative glass, we cover nearly all the traditional IR and UV materials as well as many of the rarer, more exotic ones. We have an extensive inventory of stock windows, lenses and prisms as well as raw material ingots ready for custom manufacture.
Our optical workshops are full of specialist polishing equipment which allows us to accommodate a variety of custom requirements in both prototype and production volumes. From conventional pitch polishing to lapping and double sided polishing, we can select the best method for achieving optimal flatness, parallel and surface quality specs.
Our capabilities include:
Blank forming: flats, lenses, prisms, and custom geometries
Smoothing: surface grinding and prepolishing
Pitch polishing: for optimal surface finish < 20/10
Lapmaster polishing: for surface flatness up to L/20
Double sided polishing: for high volume and tight parallel specs
Specialist polishing: for more unconventional materials like KRS-5
Inspection areas: for testing all optical and physical parameters
